5 Key PCB Layout Considerations for Efficient Circuit Board Assembly and Soldering Production Processes
When designing a PCB layout, various questions inevitably arise. Is this PCB best suited for a single-layer, double-layer, or multi-layer configuration? How should you protect against ESD/EMI? Will the printed circuit board assembly (PCBA) use a single-sided or double-sided process? … Continue reading

How to Evaluate the Risk and Probability of Electronic Components Not Falling Off during SMT Second Reflow
PCB assembly through SMT double-sided reflow soldering has become the mainstream process in contemporary electronic manufacturing. However, occasionally, many individuals inquire, “Is there a method to proactively determine, or is there any calculation formula to predict the risk or rate … Continue reading

What is OSP (Organic Solderability Preservative) Surface Treatment for PCB? What are its Pros and Cons?
OSP (Organic Solderability Preservative) is a special chemical coating applied to the surface of copper on a PCB (Printed Circuit Board). This coating forms a thin protective film that keeps the bare copper from rusting or corroding when it’s stored. … Continue reading
